Microblogging as one kind of social media application provides an important information sharing platform. Adaptive information sharing is the combination of adaptive information technologies (IT) use behavior and information sharing behavior and subsequently refers to adaptive use of IT oriented to information sharing. The purpose of this paper is to understand adaptive information sharing in the context of microblogging from the perspective of cognitive switching.

A research model was developed and survey data were collected. The partial least squares structural equation modeling was employed to verify the research model.

Adaptive information sharing is positively impacted by other people’s use, discrepancies and deliberate initiatives among which other people’s use is the key determinant. Meanwhile, task self-efficacy positively moderates the effect of other people’s use on adaptive information sharing.

Developers of microblogging should as far as possible create learning atmosphere and learning culture. With learning atmosphere and culture, more and more users could keep on learning from observing other people. Consequently, more and more users would be willing to try new features of microblogging to share information.

This study examines adaptive information sharing by extending adaptive IT use behavior from the levels of technology, system and feature to the information level, presenting a new lens for adaptive IT use and information sharing alike.

Digital libraries and social media have emerged as two prominent online information sources with different characteristics. The purpose of this paper is to compare digital libraries and social media from the perspective of the dual route model which outlined a general framework of central and peripheral route-induced attitude change.

Research hypotheses were developed and data collected from users of digital libraries and social media were used for data analysis. The paired samples t-test was employed to compare the means.

Both central route (information quality) and peripheral route (source credibility and reputation) of digital libraries are higher than those of social media.

The important status of digital libraries as conventional information sources should be propagated by various “marketing” ways. Managers of digital libraries should encourage their users to use both digital libraries and social media so that some unique advantage of social media could usefully complement digital libraries. They should also recognize the challenge brought by social media and try various ways to enhance reputation.

Building on the dual route model, this study compares digital libraries and social media in terms of the central route and peripheral route, which the authors believe presents a new lens for digital library research and practice alike.

This study aims to explore the mechanisms of extended information seeking, which is the combination of extended information technologies (IT) use behavior and information-seeking behavior. The purpose is to identify the factors that shape extended information seeking from the perspectives of psychological empowerment and attachment.

A research model was developed based on prior theory and literature. Survey data were collected, and the partial least squares (PLS) structural equation modeling was used to verify the research model.

Psychological empowerment is a well-constructed second-order construct, having a larger positive effect on extended information seeking. Digital libraries attachment has a positive effect on extended information seeking.

Accessing digital libraries does not mean using digital libraries effectively. Managers of digital libraries should design various specific information activities to help users enhance psychological empowerment. They should provide more available and responsive services for users to enhance digital libraries attachment.

Drawing on the adaptive structuration theory, this study examines extended information seeking by combining extended use of digital libraries and information seeking, presenting a new lens for digital library and information seeking research.
